PHP 7 Issues

I just tested PHP 7 to create a compatibility list of themes and plugins.

Enfold throws an error:
[error] 10811#10811: *59 FastCGI sent in stderr: “PHP message: PHP Fatal error: Uncaught Error: Function name must be a string in /htdocs/wp-content/themes/enfold/framework/php/class-style-generator.php:123

Happy debuging ;-)
